legend: RED = 4GA POWER WIRE (to sub amp) BLUE = 8GA POWER WIRE (to speaker amp) also keep in mind i crossed out the 2nd fuse to show their will be no fused used in that slot this is an three 4ga in > two 8ga out. the right side with the red is the "in" parts can i do this with a fused distro block? i will have the speaker amp fused, but the sub amp will just be a "run-a-around" situation. of course, the fuse on the amp will be matched up with the fuse by the battery. speaker amp is 25a while sub amp is 60a. i will use an 80a or 100a by the battery.
